decreasing delirium through music in critically ill older adults

Conditions: Intensive Care Unit Delirium; Pain; Anxiety; Intensive Care Acquired Cognitive Impairment

Summary: critically ill older adults admitted to the intensive care unit (icu) are at a higher risk to develop delirium, which predisposes them to longer lengths of icu and hospital stay, increased in-patient mortality, and higher risk of new acquired cognitive impairment and dementia. music listening is a non-pharmacological intervention that holds potential to decrease icu delirium. the investigators propose a randomized controlled trial to evaluate the efficacy of a seven-day slow-tempo music intervention on the primary outcome of delirium/coma free days among mechanically ventilated, critically ill older adults.

one million adults in the united states receive mechanical ventilation for acute respiratory failure in the intensive care units (icus) annually and up to 80% of them develop delirium during their icu stay. presence of delirium predisposes older adults to immediate in-hospital complications including a longer length of icu and hospital stay, increased risk of in-patient mortality and elevated costs of care. in addition, icu delirium is associated with long-term post-discharge complications such as development of cognitive impairment and dementia. recent research studies exploring pharmacological strategies to manage icu delirium have not demonstrated efficacy; a limitation also acknowledged in the society of critical care medicine 2018 pain, agitation/sedation, delirium, immobility, and sleep disruption guidelines. music listening is a non-pharmacological intervention that has shown to decrease over-sedation, anxiety and stress in critically ill patients, factors that could predispose to icu delirium. our team is now proposing to conduct a large randomized clinical trial called "decreasing delirium through music (ddm) in critically ill older adults to evaluate the efficacy of a seven-day slow-tempo music intervention on the primary outcome of delirium/coma free days among mechanically-ventilated older adults admitted to the icu.
